Air purification system and method for maintaining nitrogen and oxygen ratios with regenerative purification units

A process for the purification of air, whereby the ratio of nitrogen to oxygen is maintained in said air, comprising the steps of:

• a step for removing a first portion of water from said captured air, wherein semi-dried air results from said removal step, whereby said semi-dried air is less than 10,000 ppm of water vapor;
• flowing said semi-dried air through a first adsorption column in a first flow direction, whereby said dried air is semi-purified, wherein said flowing dried air through said first adsorption column includes the removal of moisture and carbon dioxide semi-purified air;
• flowing said semi-purified air through an oxygen catalyst, wherein hydrocarbons carbon monoxide in said semi-purified air are converted in carbon dioxide and water, whereby oxygenated semi-purified air results;
• flowing said oxygenated semi-purified air through a second adsorption column in a second flow direction;
• wherein said flowing through said second adsorption column includes removing remaining carbon dioxide, water and oxides of nitrogen from said oxygenated semi-purified air, whereby creating purified air with contaminants less than 10 parts per billion.

A process for purifying air including the steps of:

• during time interval T, flowing unpurified air through a first adsorption column, in a first flow direction, resulting in a stream of semi-purified air;
• flowing said semi-purified air through a oxygen catalyst, resulting in oxygenated semi-purified air, and flowing said oxygenated semi-purified air through a second adsorption column in a second flow direction, wherein a third adsorption column has purified air flowing through it;
• during time interval, T+1 time unit, said third adsorption column has said unpurified air flowing through it in a first flow direction, and said first adsorption column receives purified air from a source which is connected to said second adsorption column;
• and
• during time interval, T+2 time units, said first adsorption column has said oxygenated semi-purified air flowing through it in a second flow direction, and said second adsorption column has purified air flowing through it.

An air purification system, comprising:

• an air intake and an air outflow and tubing;
• a compressor connected to said air intake;
• a water trap connected to said compressor, said water trap for removing water from air;
• a set of more than one adsorption columns;
• and
• an oxygen catalyst unit;
• wherein said air is passed through said tubing from said water trap through a first of said set of adsorption columns, then passed through said oxygen catalyst unit, and then passed through a second of said set of adsorption columns, and optionally, said air outflow.

An air purification system, comprising:

• an air intake and air outflow and tubing;
• a compressor connected to said air intake;
• a water trap connected to said compressor, said water trap being for removing water from said air;
• a set of more than one adsorption columns, wherein said air is passed through said tubing from said water trap before being passed though a first of said set of adsorption columns, whereby the life of said first adsorption column is extended.

An air purification system comprising:

• tubing;
• said tubing for directing a flow of air;
• a set of more than one adsorption columns;
• a unit including an oxygen catalyst;
• wherein said air flows through said tubing to a first of said set of adsorption columns and flows from said first adsorption column to said oxygen catalyst unit, and flows from said oxygen catalyst unit to a second of said set of adsorption columns.
